--to calculate song lengths: 
-- given a song length of 3:15 as an example.
-- 1. Multiply 3 * 60 (since there are 180 seconds in 3 minutes)
-- 2. add + 15 (since there are 15 additional seconds in the song
-- 3. multiply the entire result by 30 (since there are 30 ticks in one second)
-- RESULT: (3 * 60 + 15) * 30 for a 3:15 long song.
